A Phylogeny Of The Snappers (Lutjanidae; Percoidei) Inferred From Cytochrome B Sequence Data, Matthew R. Semcheski
A Phylogeny Of The Snappers (Lutjanidae; Percoidei) Inferred From Cytochrome B Sequence Data, Matthew R. Semcheski
Biological Sciences Theses & Dissertations
The Lutjanidae are economically and ecologically important fishes commonly known as snappers. A morphological study of Lutjanidae concluded that it contained four subfamilies and that together with the family Caesionidae, form the superfamily Lutjanoidea. Although this view was supported elsewhere in the literature, it was later contradicted, treating the caesionids as members of the Lutjanidae. In order to infer a phylogeny of genera within Lutjanidae, the complete cytochrome b gene (1140bp) of 21 lutjanid taxa was sequenced and analyzed along with 19 lutjanid, caesionid, and outgroup sequences obtained from GenBank. Data were analyzed for base composition stationarity and saturation. Phylogenetic …
Nutritional Condition Of Striped Bass (Morone Saxatilis) Larvae As Determined By Constituent Lipid Analysis, William Frank Patterson Iii
Nutritional Condition Of Striped Bass (Morone Saxatilis) Larvae As Determined By Constituent Lipid Analysis, William Frank Patterson Iii
Biological Sciences Theses & Dissertations
Larval striped bass were reared in the laboratory from 6 days post-hatch (dph) to 21 dph under four different feeding regimes to assess the effect of food concentration on triacylglycerol to sterol ratios (TG:ST) of larvae. Larvae were fed Peru strain Artemia salina nauplii in concentrations of 0, 10, 100, and 10001·1-1, with three replicate tanks within each feeding treatment. Larvae were sampled on 14 and 21 dph and frozen in liquid nitrogen. Lipids were extracted from larvae in a 90:10:1 solution of dichlormethane:hexane:formic acid and analyzed with thin-layer chromatography/flameionization detection. Analysis of larval constituent lipids, and calculation …
Morphological Variation Among 14 Species Of Callogobius Bleeker (Pisces: Gobiidae), James Francis Mckinney
Morphological Variation Among 14 Species Of Callogobius Bleeker (Pisces: Gobiidae), James Francis Mckinney
Biological Sciences Theses & Dissertations
A survey of the variation among the species of the Callogobius complex has been accomplished in order to determine if recognition of more than one genus is warranted for this assemblage of species. Emphasis has been placed on the osteological variation. Relationships among certain species within the Callogobius complex have been exposed. Although there are two well defined species groups within the complex, it is felt that inclusion of all of the examined species within the single genus Callogobius is the most parsimonious course of action.
